I Became a Jujutsu Sorcerer, Yet I'm Still the Strongest

As the Port Mafia's undisputed strongest, Mori Ougai has always been proud to have such an outstanding, responsible, and capable subordinate as Nakahara Chuuya. Until one day-- "Boss! Mr. Nakahara says he's quitting!" "...?" The black-haired man smiled and asked, "Why is Chuuya-kun quitting?" His subordinate replied, "Mr. Nakahara says he's going to become a jujutsu sorcerer." "..." Mori Ougai: What the hell? "Boom--" As the dust settled, an orange-haired boy could be seen dropping from the sky, one foot planted on a curse's head and forcing it into the ground. He held down his hat as his black coat whipped wildly in the wind, his cobalt-blue eyes full of disdain. "Who did you say you were going to kill?" "Say it again." The curse: "...%#￥*&" Who sent me after Nakahara Chuuya?! Are they trying to get me killed?! Nakahara Chuuya, formerly an executive in Yokohama's Port Mafia, the Arahabaki incarnate, with the ability "Upon the Tainted Sorrow." For some reason, one day he suddenly quit the Port Mafia, then went on to become one of the handful of special-grade jujutsu sorcerers. After exorcising another curse, the orange-haired boy brushed the dust off his hat, then noticed the gaze clinging to him from beside him. He looked over, puzzled. "Why do you keep staring at me?" "Nothing." The white-haired, blue-eyed young man shook his head. "I was just thinking that Chuuya really is the strongest." "..." The boy put his hat on and turned his head away awkwardly. "Tch, obviously." --And I'm the strongest, after all. That was what Gojo Satoru thought at that moment. Tips: The pairing is probably strongest x strongest. My version of Chuuya is very out of character. I changed the blurb again. [I'm such a blurb-changing maniac] Theme: I became the strongest after changing careers to a jujutsu sorcerer.
